CAN-HEADING MACHINE.

A li ati fil d October 17, 1899. Serial No, 733,856. (No model.)

To rtZZ whom it may concern.-

Be it known that I, ERNEST O. Arrwoon, a citizen of the United States, residing at Goldengate, county of Alameda, State of California, have invented an Improvement in Can- Ileading Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device for heading cans of that class in which the body is made of pasteboard or like material with metallic or other bottom and metallic or other head, the object being to apply-and crimp the metallic ring by which the head is secured upon the top of the can after the latter has been filled.

My invention comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is an elevation of the device. Fig. 2 is a vertical section through the crimping device. Fig. 3 is a horizontal section on line 2 3 of Fig 2.

A is a frame or support of any suitable or desired character, having an extension or bracket A at the top,within which is journaled a shaft B, through which power is applied. Upon this shaft is fixed a bevel-gear C,and this engages a corresponding pinion D upon a Vertical sleeve E. This sleeve is turnable around a central shaft F, extending from the upper part of the bracket A downwardly and having fixed upon its lower end a head G. A vertical hollow guide H is supported from the frame A, and through this guide extends a vertical shaft or spindle I, having upon its upper end a table J, axially coincident with the disk G, and the can to be headed is supported upon this disk or table J, and after the cover or head has been placed upon it it is moved up into contact with the disk G, where it is retained by means of a treadle K and connecting-rod L, intermediate between the treadle and the shaft or spindle I. In

this position the can remains stationary. A spiral spring 0 surrounds the shaft I between the table J and the top of the guide H, as shown, exerting a slight upward pressure upon the table.

The cap or cover P rests upon the upper dented into the upper part of the can by the following apparatus: The lower end of the sleeveE has a disk or flange c, and upon the periphery of this flange are fixed the fulcru ms S, in which the arms T are pivoted. Any suit.- able number of these arms may be thus fulcrumed or pivoted to the periphery of the disk. I have found that three, equally interspaced, is a very suitable number for the work. Upon the lower ends of these arms are carried the semiglobnlar heads U, having a circumferential bead V formed about the upper portion, which forms the larger diameter of the hemispherical segment, and through the center of which surface the arm T passes axially, being secured by a nut or other device at the lower end. These arms are connected by links a with lugs b, to which they are pivoted, the links being also pivoted to the upper ends of the arms T. The lugs b are fixed to the lower part of a sleeve 0, which is vertically slidable by reason of a spline d thereon engaging a groove in the side of the sleeve E.

The sleeve or collar 0 is slidable upon the sleeve E by means of a lever f, fulcrumed upon the bracket A, and a connecting-rod g extends from the outer end of the leverf down to a treadle h, which is within reach of the operator.

The operation would then he as follows: The can having been placed upon the table J, with its cover and surrounding ring in place, is raised up into contact with the disk G and is thus centered and held stationary between these two disks. The foot of the operator being placed upon the treadle h will act through the lever fto press the collar 0 down, and this, acting through the link a, will press the upper end of the arm T outwardly. This forces the beaded edge V of the head U into contact with the side of the ring R, and as the arms T are revolved in unison with the revolution of the disk e on the sleeve E, to which motion is transmitted through the bevel-gears C and D, previously described, it will be seen that the heading V of the spherical heads will be pressed against the ring R and rapidly revolved around the can until the ring has been crimped and indented sufficiently to secure it firmly upon the head of the can. In this manner I am enabled to rapidly head this class of cans after they have been filled and provide a tight closure therefor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A device for applying heads upon the ends of cans in which the heads rest upon the can ends, and are inclosed by annular rings extending over the head and down the side of the can, said device comprising a frame having upper and lower guides,vertical shafts mounted in said guides one of said shafts having a spring-seated table to support the can and the other shaft having an encircling sleeve provided with a disk to restupon the can-head, a collar splined on the sleeve, and a treadle and connections for raising the lower shaft, fulcrum-arms projecting from the disk and the collar, arms fulcrumed between their ends to the arms on the disk and having their lower ends provided with semiglobular beaded heads, links having one end connected with the arms on the collar and their opposite ends pivotally connected with the upper ends of the arms which carry the beaded heads, alever connected with the collar and a treadle and connection for operating the same whereby the beaded heads are moved into and out of contact with the securing-rings of the can, and means for rotating the upper shaft.

2. In a machine of the character described, the combination of means for supporting the can, a Vertical shaft and means for rotating the same, a sleeve surrounding the shaft and a collar splined on said sleeve,arms fulcrumed to the sleeve at points between their ends and having their lower portions threaded, semiglobular heads fitted to the lower ends of the arms and having beaded peripheries, nuts engaging the threaded ends of the arms and securing the heads in place and links fulcrumed to the collar and having their lower ends pivotally connected to the upper ends of the arms.

In witness whereof I have hereunto set my hand.
